Slew Drives

Slewing rings with integral worm shafts are becoming increasingly popular due to the simplicity of installation and are used in truck mounted cranes, access platforms, turntables, solar tracking devices, satellite communication systems, small wind turbines (yaw axis) and simple materials handling devices. NBC imports a range of standard ENCLOSED slew drives including the WGSE (helical gear/ worm shaft); WGWEA (worm gear/worm shaft); WGHSE (increased performance for modular transporters) and WGR (Rotation drives). Dual drive and the lighter OPEN gear systems (WGS) are catalogued but will be imported to order only. High precision and zero backlash units are similarly only imported against specific projects. NBC can offer various electric and hydraulic motors and gearboxes to suit.
